Phantom sensations after excision of the rectum

Forty consecutive patients were questioned after proctectomy to ascertain the presence and characteristics of phantom sensations. Twentysix (65 per cent) reported the presence of these sensation. Once established, the sensations were permanent in 20 patients; in six, they disappeared after a variable lapse of time. The most frequent sensation was an urge to defecate, which may be very disturbing to the patient. Explanation of the phenomenon usually is sufficient to alleviate anxiety.

A small leiomyosarcoma of the pancreas treated by local excision

BackgroundLeiomyosarcoma of the pancreas is a very rare tumour; only 33 cases have been reported in the English literature. Because these tumours tend to be large and locally advanced, extended resection such as pancreatoduodenectomy or distal pancreatectomy has been advocated.Case outlineA 25-year-old woman with left-sided back pain had a small low-density lesion (2×2 cm) in the pancreatic body on computed tomography (CT). The tumour was initially diagnosed as a pseudocyst and was managed conservatively. A repeat CT scan 10 months later showed an increase in the size of the lesion (3.5×3.5 cm) with contrast enhancement of a high-density area. The diagnosis was therefore changed to papillary-cystic neoplasm. At laparotomy, the tumour seemed to be arising from the mid-body of the pancreas with no invasion into surrounding organs. Local excision of the tumour was performed. Pathological examination revealed a leiomyosarcoma of the pancreas.DiscussionComplete surgical resection offers the only potential chance of cure for patients with leiomyosarcoma of the pancreas.The lack of evidence of recurrence at three-and-a-half years suggests that the less invasive surgical procedure in the present case has been curative. Careful and intraoperative exploration was important to determine the best surgical procedure.     

Still any role for transduodenal local excision in tumors of the papilla of Vater?

Tumors of the papilla and ampulla of Vater are rare neoplasms which are usually detected at an early stage due to their symptoms. The accurate preoperative histological diagnosis and staging of ampullary tumors is often difficult and inconclusive, leading to controversy over the adequate treatment of these lesions. Three procedures are currently being used to treat such tumors. Pancreatoduodenectomy (PD) is a procedure with low morbidity and mortality at experienced centers, and is considered the treatment of choice for invasive carcinoma and large benign ampullary lesions with suspicion of malignancy. Transduodenal local excision (TDE) of ampullary tumors is a relatively simple procedure with operative morbidity and mortality rates comparable to PD. TDE is challenged at endoscopic centers by endoscopic snare excision (ESE). Due to technical advances, the safety and outcomes of ESE for ampullary tumors have improved in recent years. ESE and TDE represent adequate methods for treatment of benign tumors and also for small malignant tumors detected at an early stage if the diagnosis and stage have been accurately established preoperatively. Due to the safety of PD and the technical advances of ESE, TDE is reserved for selected patients. Randomized controlled studies are needed to establish the correct indications for PD, TDE, and ESE.     

Symptomatic recurrences of carcinoma of the rectum and sigmoid

One hundred forty-three patients irradiated for locoregional recurrences after curative surgery for cancer of the rectum and sigmoid were studied retrospectively. An analysis was made of the symptomatic response and survival in the total series and in three subgroups treated with different dose levels (40 Gy or lower, between 40 and 50 Gy, 50 Gy or higher). The symptom-free period was calculated as percent of the overall survival. Symptomatic control was obtained in 80.4 percent of the cases, and the crude patient survival rate was 17.5 percent at two years. No significant difference was found in the three subgroups treated with different dose levels. The cumulative time/patient asymptomatic periods in the total series and in the three subgroups were 31.5, 30.2, 31.8, and 31.9 percent respectively, of the survival period.     

Preoperative radiation therapy with sensitizers in the management of carcinoma of the rectum

There is enough evidence to show that adjuvant radiation therapy contributes to the management of patients with carcinoma of the rectum. In an effort to improve resectability and possibly survival rates, the use of chemosensitizers, combined with moderate doses of radiation used presurgically, was introduced for carcinomas larger than 5 cm in diameter requiring abdominoperineal resection. Based on our experience and that of others, it is believed that the method of administration of 5FU and mitomycin-C is an important factor in obtaining an increased therapeutic ratio. Because of the locoregional pattern of spread of rectal cancer, this adjuvant approach would appear suitable. A series of approximately 60 patients is discussed and the surgical findings and five-year survival is reported.

Teflon® felt for closure of the pelvic floor after abdominoperineal excision of the rectum

Teflon^® felt has been used in ten patients without complication or delay in healing, as a satisfactory means of closing a large gap in the peritoneal floor after abdominoperineal excision of the rectum. The technique is described.     

Acid burns of the rectum and colon

The case of a patient with acid burns of the large bowel from a self-administered enema of 95 percent sulfuric acid solution is reported. The authors were unable to find a similar case in the English medical literature. The patient presented in metabolic acidosis, and flexible sigmoidoscopy was of limited value. Peritoneal signs warranted early laparotomy, which revealed coagulation necrosis of the anus, rectum, and colon up to the hepatic flexure without any free perforation. The extent of damage was more severe than seen in the upper digestive tract from acid ingestion. Juxtaposed small bowel and the appendix sustained serosal burns. Subtotal proctocolectomy and perineal resection were done and the patient made an uneventful recovery. Early laparotomy is warranted, irrespective of endoscopic findings, for appropriate surgical correction.     

Internal intussusception of the rectum

Internal intussusception of the rectum is described as a specific clinical entity. A review of the cases treated at the Colon and Rectal Surgery Service at Jewish Hospital is presented, along with the specific diagnostic procedures that have been developed and the surgical technique that allows relatively simple correction of the problem. It is believed that this entity presents commonly to the practitioner of colon and rectal surgery, and specific diagnoses and therapy will be an important addition to the armamentarium of the colon and rectal surgeon.

Long-term survivors with nonresectable advanced carcinoma of the rectum

Two patients with advanced rectal cancer, women aged 73 and 49 years, have survived more than nine years with chemotherapy only and no surgical removal of the disease foci. In one patient, the tumor completely disappeared, and in the other the tumor stopped growing and its size remained unchanged. The reason for this long-term survival appears to be a high susceptibility to anticancer agents and persistence of enhanced host immunity.     

Local recurrence after curative resection of cancer of the rectum without total mesorectal excision

PURPOSE: The aim of this article was to examine local recurrence after curative resection for carcinoma of the rectum in which the surgical technique of total mesorectal excision was not performed. METHODS: A single surgeon managed the patients and the data collected prospectively. Total excision of the distal mesorectum was not performed in the upper third or mid rectum. RESULTS: From 1969 to 1993 curative resections were performed in 549 patients, of which 17 died postoperatively, leaving 532 for analysis. Sphincter-saving resection was performed in 468 patients (88 percent) and abdominoperineal excision in 58 (10.9 percent). The pathology stages (Dukes) were A, 158 (29.7 percent); B, 184 (34.7 percent); and C, 190 (35.7 percent). Five hundred seventeen patients (97.2 percent) were followed up for a minimum of five years. The median period of follow-up was 82 months. Local recurrence confined to the pelvis occurred in 17 patients, and local recurrence associated with distant metastases occurred in 24 patients. The total five-year local recurrence rate was 7.6 percent. Local recurrence was increased in Stage C tumors (P=<0.0001). Diathermy dissection in the pelvis was associated with a decreased local recurrence rate (P=0.023). The five-year survival rate in curative resections was 72.5 percent. CONCLUSIONS: It is essential that articles presenting local recurrence rates should include both local recurrence in isolation and that which occurs with distant metastases. Although total mesorectal excision for rectal cancer was not performed in this study, the local recurrence rate is not materially different from that in several articles where total mesorectal excision has been used. Whether the distal mesorectum needs to be pursued in mid-rectal cancer is not yet proven.     

Prognostic correlations of operable carcinoma of the rectum

Various histologic factors correlated to survival were studied in 124 patients radically operated on for rectal carcinoma in order to establish valid prognostic criteria. The total survival rate after five years was 63 percent, while in stage B1 it was 89 percent, in B2, 61 percent, and in C1, 47 percent (P<0.05). With regard to histotype, the survival was 83 percent in the papillary subtype of adenocarcinoma, while in the tubular subtype it was 62 percent, and 29 percent in the mucinous type (P=not significant). Vascular invasion negatively affected survival (41 percent); however, when there was no invasion, the prognosis was better (71 percent) (P<0.01). In evaluating histologic grading and lymphoglandular reactivity, the difference in survival rates was not statistically significant. The marked peri- and intratumoral lymphocytic infiltration gave a very good prognosis (92 percent) contrary to when reactivity was moderate (59 percent) or even absent (51 percent) (P<0.01). Finally, the expanding type tumor, with reference to Ming's classification of gastric carcinoma, had a much better prognosis (75 per cent) than the infiltrative type (40 percent) (P<0.01).
