"Two Hospitals Told Me I Would Need a Permanent Colostomy Bag for the Rest of My Life." She Was 45. Low Rectal Cancer. A Tumor Close to the Anal Verge. Every Surgeon She Saw Said the Sphincter Had to Go. One Last Hope.
Ms. Chen had always been someone who moved fast.
A 45-year-old marketing director, she lived at the pace her career demanded — early mornings, client meetings, international travel, a social life she had built carefully over two decades. She was the kind of person who planned ahead, who managed risk, who kept things under control. She had never thought much about her body. It had always simply worked.
The diagnosis arrived without warning.
A routine health check. A colonoscopy. A biopsy. Then a call from her doctor with words she had not prepared for: low rectal adenocarcinoma. A malignant tumor in the lowest portion of her rectum, close to the anal verge — the opening of the anus itself.
She went to the first hospital. The surgeon reviewed her MRI and was direct: the tumor’s position made sphincter preservation impossible. A standard Abdominoperineal Resection (APR) was necessary — removal of the rectum, the anus, and the sphincter muscle. She would require a permanent colostomy: a surgically created opening in her abdomen through which her bowel would empty into a bag attached to her skin, for the rest of her life.
She went to a second hospital. The answer was the same.
Ms. Chen sat with that information for three days. She thought about what it would mean — not just medically, but in every dimension of the life she had built. The travel. The client dinners. The relationships. The mornings. She was 45 years old. She was not ready to accept that this was the only path.
She asked her oncologist if there was anyone else. Anyone who might see the imaging differently. Anyone who might try.
She was referred to Dr. Cai Sanjun, Chief of Colorectal Surgery at Fudan University Shanghai Cancer Center, through China Medical Concierge – Shanghai (CMCS).
Understanding Low Rectal Cancer Surgery: Why Specialist Expertise Is Everything
Rectal cancer surgery is among the most technically demanding procedures in abdominal oncology. The rectum sits deep in the bony pelvis, surrounded by critical structures — the bladder, the urethra, the pelvic nerves controlling continence and sexual function, and, at its lowest extent, the anal sphincter complex. When a tumor is located in the lower rectum, close to the sphincter, the surgical decision between sphincter preservation and permanent colostomy is one of the most consequential choices in cancer care:
- The distance between tumor and sphincter determines what is surgically possible — achieving a clear oncological margin (R0 resection) requires removing the tumor with an adequate margin of healthy tissue below it; when a tumor is located very close to the anal verge, the margin between oncological safety and sphincter preservation narrows to millimeters; the ability to operate safely within that margin requires both advanced technique and precise preoperative planning
- Neoadjuvant chemoradiotherapy can convert an inoperable sphincter into a preservable one — for tumors that are borderline in terms of sphincter proximity, preoperative chemotherapy and radiation can shrink the tumor, increasing the distance between its lower margin and the sphincter complex; this downsizing strategy, when carefully planned and monitored, can transform a case that requires APR into one where sphincter-preserving surgery is oncologically safe
- Total Mesorectal Excision (TME) is the oncological gold standard — and its quality determines recurrence risk — TME involves the precise surgical dissection of the rectum within its surrounding mesorectal envelope, removing the primary tumor and all regional lymph nodes in a single intact specimen; the quality of TME is the single strongest predictor of local recurrence; a high-quality TME in the hands of an experienced surgeon reduces local recurrence rates to below 5%
- Laparoscopic surgery in the deep pelvis demands exceptional technical skill — performing TME laparoscopically — through small keyhole incisions rather than a large open wound — requires the surgeon to operate in a confined anatomical space with limited instrument maneuverability; the learning curve is steep, and outcomes are directly correlated with surgical volume and subspecialty experience
- A temporary protective ileostomy is not a permanent colostomy — when sphincter-preserving surgery is performed for low rectal cancer, a temporary ileostomy is often created to divert the bowel away from the anastomosis while it heals; this temporary stoma is planned for reversal, typically at three months, and is fundamentally different from the permanent colostomy required after APR; the distinction matters enormously for the patient’s long-term quality of life
- Functional recovery after sphincter-preserving surgery is a process — and it is achievable — bowel function after low anterior resection requires a period of rehabilitation; frequency, urgency, and clustering of bowel movements are common in the early months and improve progressively with time and structured rehabilitation; the majority of patients achieve satisfactory functional outcomes within six to twelve months, and the long-term quality of life advantage over permanent colostomy is well-established in the literature
About Dr. Cai Sanjun 蔡三军
Dr. Cai Sanjun is the Chief of Colorectal Surgery at Fudan University Shanghai Cancer Center (FUSCC) — China’s premier oncology institution and one of the highest-volume cancer surgery centers in Asia. Nationally recognized not only for his surgical volume but for his dedication to quality-of-life outcomes, Dr. Cai is one of China’s leading advocates for sphincter-preserving surgery in low rectal cancer. He has led landmark multicenter clinical trials that have shaped the national guidelines for colorectal oncology in China, and his department serves as a training hub for colorectal surgeons from across the country. For patients who have been told that a permanent colostomy is their only option, Dr. Cai’s practice at FUSCC represents a genuine second opinion — and, for many, a different answer.
His clinical expertise spans:
- Sphincter-preserving surgery for low rectal cancer — advanced laparoscopic Low Anterior Resection (LAR) with Total Mesorectal Excision for tumors at or near the anal verge, including ultra-low resections in patients who have been advised to undergo APR elsewhere
- Neoadjuvant therapy coordination for borderline cases — multidisciplinary planning of preoperative chemoradiotherapy to downsize tumors and expand the pool of patients eligible for sphincter-preserving resection
- Laparoscopic colorectal oncology — minimally invasive surgery for colon and rectal cancer across all stages, including complex cases involving adjacent organ involvement, prior pelvic surgery, and obesity
- Total Mesorectal Excision (TME) — high-quality mesorectal dissection with consistently low local recurrence rates, reflecting the technical precision and surgical volume of Dr. Cai’s department
- Multidisciplinary colorectal cancer management — coordination of surgical, oncological, radiological, and rehabilitation expertise within FUSCC’s integrated colorectal cancer program
- Clinical trial leadership — principal investigator on multicenter trials defining the evidence base for sphincter preservation, neoadjuvant therapy protocols, and functional outcomes in rectal cancer surgery across China
The Case That Proved a Permanent Colostomy Was Not the Only Answer
The Situation
A 45-year-old marketing director. Low rectal adenocarcinoma with the tumor located close to the anal verge. Advised by two separate hospitals that Abdominoperineal Resection — with permanent colostomy — was the only safe surgical option. A patient for whom the psychological and social impact of a permanent stoma was devastating, and who was not prepared to accept that verdict without a second opinion from the highest available expertise. One question: is there a surgeon who can look at this MRI and find a path to removing the cancer without removing the sphincter?
The Assessment
Dr. Cai reviewed Ms. Chen’s MRI and endoscopic ultrasound with the systematic attention of a surgeon who has spent a career measuring millimeters in the deep pelvis. He assessed the tumor’s lower margin, its relationship to the sphincter complex, the quality of the mesorectal envelope, and the lymph node status. His reading of the imaging was precise: the distance between the tumor’s lower border and the sphincter was narrow — but it was not zero. There was a margin to work with. Not a comfortable margin. Not a margin that made the surgery straightforward. But a margin that, in the hands of a surgeon with his experience and with the right preparation, made sphincter preservation oncologically feasible.
He convened a Multidisciplinary Team (MDT) discussion — bringing together colorectal surgeons, oncologists, and radiologists to review Ms. Chen’s case collectively. The team agreed: a course of neoadjuvant chemoradiotherapy before surgery could shrink the tumor, increasing the safety margin and reducing the risk of a positive resection margin. The plan was explained to Ms. Chen in full.
In the consultation, Dr. Cai told her what he tells every patient in this situation:
“Curing the disease is our primary goal, but restoring the patient to their life is our mission. If we can remove the cancer safely without sacrificing the anus, we owe it to the patient to try. In colorectal cancer, the surgery changes the patient’s body forever. We must be radical enough to cure the cancer, but delicate enough to preserve their humanity. A permanent stoma is sometimes necessary — but it should not be the default option if technology and skill can offer a better path.”
Ms. Chen completed the neoadjuvant course. The tumor responded. The imaging confirmed the increased margin. Dr. Cai confirmed the surgery could proceed.
The Procedure
The surgery was performed using Dr. Cai’s advanced laparoscopic technique — several small keyhole incisions in the abdomen, avoiding the large open wound of conventional surgery and its associated recovery burden.
Working deep in the pelvis through the laparoscopic approach, Dr. Cai performed a meticulous Total Mesorectal Excision (TME) — dissecting the rectum and its surrounding mesorectal envelope in a single intact specimen, removing the primary tumor and all regional lymph nodes while preserving the pelvic nerves controlling continence and sexual function. The dissection proceeded to the level of the sphincter complex. With precise technique in the narrow confines of Ms. Chen’s pelvis, he achieved the distal margin required for oncological clearance — and preserved the sphincter intact.
A colorectal anastomosis was constructed — reconnecting the bowel above the preserved sphincter. To protect the anastomosis during healing, a temporary loop ileostomy was created: a planned, reversible diversion, not a permanent colostomy. The plan for reversal was set from the first day of recovery.
The Recovery
Pathology confirmed what Dr. Cai had planned for: clear margins on all sides (R0 resection). No lymph node involvement. The cancer had been removed completely.
Three months after surgery, Ms. Chen returned to FUSCC. The temporary ileostomy was successfully reversed. Her bowel was reconnected. The stoma bag — always temporary, always planned for closure — was gone.
In the months that followed, her bowel function recovered progressively. Frequency was higher than normal at first — a predictable consequence of low anterior resection that Dr. Cai’s team had prepared her for — and improved steadily with the structured rehabilitation program. By six months, she had regained satisfactory bowel control.
She returned to work. She traveled for a client meeting. She went to dinner with friends. She did not carry a bag. She did not explain herself to anyone. She was, in every way that mattered to her, whole.
She sent a message to CMCS six months after the stoma reversal. It said: “I went back to the city where I had my first consultation. I walked past the hospital that told me I had no choice. I kept walking.”
Outcome Summary
- ✅ R0 resection confirmed — pathology confirmed clear margins on all sides with no lymph node involvement, achieving the complete oncological clearance that is the primary goal of rectal cancer surgery
- ✅ Sphincter preserved — permanent colostomy avoided — laparoscopic sphincter-preserving Low Anterior Resection successfully performed in a patient advised by two prior centers that Abdominoperineal Resection with permanent colostomy was the only option
- ✅ Temporary ileostomy reversed at three months — the protective loop ileostomy was successfully closed at the planned three-month mark, eliminating the stoma entirely
- ✅ Satisfactory bowel function restored by six months — progressive functional recovery with structured rehabilitation, achieving satisfactory bowel control within six months of stoma reversal
- ✅ Full return to professional and social life — Ms. Chen returned to work, travel, and social activities without the burden of a permanent ostomy, with significant improvement in mental health and social confidence compared to the prognosis she had received elsewhere
- ✅ World-class oncological outcome at a fraction of the cost — high-volume laparoscopic rectal cancer surgery at FUSCC, one of Asia’s premier cancer centers, at a fraction of US costs, with functional and oncological outcomes that exceeded what had been offered abroad
“She was 45. Two hospitals had told her the tumor’s position made a permanent colostomy unavoidable. Dr. Cai Sanjun at Fudan University Shanghai Cancer Center reviewed the imaging, coordinated neoadjuvant therapy to increase the margin, and performed a laparoscopic sphincter-preserving resection with Total Mesorectal Excision. Pathology confirmed clear margins. Three months later, the temporary stoma was reversed. She returned to work — cancer-free, and without a bag.”
Why Shanghai for Rectal Cancer Surgery?
- World-class outcomes at a fraction of the cost — laparoscopic rectal cancer surgery at FUSCC costs a fraction of what it would in the US, with oncological outcomes, sphincter preservation rates, and functional recovery data that reflect the highest international standards, without the prohibitive costs or the waiting lists
- Highest-volume colorectal cancer center in China — Fudan University Shanghai Cancer Center is China’s premier oncology institution; the colorectal surgery department’s case volume translates directly into the technical precision and complication management expertise that determines outcomes in complex pelvic surgery
- Sphincter preservation as a genuine clinical priority — not a compromise — Dr. Cai’s department approaches sphincter preservation as an oncological and quality-of-life imperative, not a secondary consideration; the combination of neoadjuvant therapy planning, advanced laparoscopic technique, and high-quality TME enables preservation rates that are not achievable at lower-volume centers
- Multidisciplinary team decision-making as standard — every complex rectal cancer case at FUSCC is reviewed by a multidisciplinary team of surgeons, oncologists, and radiologists before a treatment plan is finalized; this collective approach ensures that the full range of options — including neoadjuvant strategies that may convert an APR case into a sphincter-preserving one — is considered for every patient
- Evidence-based practice shaped by the surgeon who writes the guidelines — Dr. Cai’s leadership of multicenter clinical trials means that his department’s protocols reflect the current frontier of colorectal oncology evidence; patients treated at FUSCC receive care aligned with the guidelines that Dr. Cai’s research has helped define
